There is no one definitive answer to this question, as everyone experiences immersion differently. However, there are some general factors that tend to contribute to a more immersive VR experience. For example, if the VR world is realistic and designed well, with believable characters and environments, it can be easier to feel immersed in it. Additionally, if the VR headset is comfortable and gives you a wide field of view, that can also help with immersion.
